CAR-COUPLING.-

SPECIFICATION forming part of Letters Patent No. 354,636,6ated December 21, 1886.

Application filed April 29, 1886. Serial No. 200,515. (No model.)

.cars. This object I attain by the means illustrated in the accompanying drawings, in which similar letters refer to similar parts throughout the several views.

Figure 1 is a longitudinal sectional view of my coupling, showing the position of the parts in readiness for the insertion of the coupling link. Fig. 2 is a sectional view, showing a coupling with a link and pin in place. Figs. 3 and 4 are Views of details to be described.

Referring to the figures, A .represents a draw-head constructed in the usual way, except that the openings k are preferably conicalshaped, terminating inwardly in a rectangular chamber, 2', of a depth horizontally of the head adapted to receive the several parts. The conical form of the opening it is for the purpose of guiding the coupling-link into the rectangular chamber Within the chamber 1' a block, a, having a slot or-opening, j, as shown in Fig. 3, is adapted to move freely.

[When the block a is in its place, the pin D is inserted in the head, and passes through the opening j in the block, which serves to keep the block in its place.

Between the block a and the bottom of the chambert the spring E is inserted, as shown in Fig. 2, in which the block is shown partially cut away, revealing the position of the pin D. Fig. 1 shows how the spring acts upon the block, forcing it outward until it is stopped by the pin D.

The head A is provided at 0 with theusual hole for a coupling-pin. In Fig. 1 is shown how the coupling-pin B, when ready for action, rests on the block a. It is obvious that when a link, as O, is forced against the block a, said block will be pushed back until the pin B will drop within the link 0 and through the movement of the block by the spring when pin B is withdrawn.

The rectangular chamber 13 is so adapted to the form of links most commonly used that when one is in place, as in Fig. 2, the outer free end of the link cannot drop so low'as to require the hand to lift it to meet the opposite draw-head.

The line G is supposed to represent the end of a car, on which a shaft, f, is supported in bearings, one of which is represented by g. This shaft may extend the width of a car, and be provided with cranks at the outer ends,- as is usual, to enable train-men to handle the coupling-pin without going between the car's.

To the shaft f, just over the draw-head, an arm, F, is attached, and by means of one or more chain-links is connected with the coupling-pin, as shown. Arm F is also connected with a chain, (1, which may pass to the top of or within a car, from which points thepin B may be operated. The action will be obvious. Turning the shaft by means of the cranks at either end of the shaft, or pulling on chain d,

will cause a lifting of the pin B from its socket, and as link 0 is withdrawn the block a will move forward under pressure from the spring E, and taking the position shown in Fig. 1, will support the pin B, as shown. A stop, m, may be applied to the shaft f to prevent lifting the pin B farther than necessary.

Fig. 4 is a top View of the draw-head A, the dotted lines indicating the shapes of the openings in the head, the coupling-pin hole 0, pin D, and the movable block a.

' 1 do not claim originality in the use of a sliding block to accomplish the purpose herein described, but that my method of adapting it to a draw-head overcomes defects that have been encountered in its'employment. Neither adapted to support a coupling-link in nearly a horizontal position and a length to receive a sliding block and spring, and terminating at its outer end in a semicircular opening, k, a

slotted sliding block, a, provided with square ends and areduced thickness at its central portion, a pin,'D, to limit the movement of block a, and having a strength equal to that of the coupling-pin, a spring, E,a shoulderless coupling-pin, B, a link, 0, an arm, F, provided with a stop, m, a shaft, f, a bearing, 9, secured tothe end of a car, and a chain, d, all operating together as herein described and set forth. 7
